Bug Description

Archive's 'suppress_subscription_notifications' attribute is called 'commercial' in the database. This creates a sheer between the code and the database, which (mixing metaphors) causes drag to developers understanding and maintaining the system. The database column should be renamed to suppress_subscription_notifications.

Steps:
1. Make code work with both.
2. Rename column in the database.
3. Remove kludges from step 1.

I suspect that this is because the qastaging database has not yet been updated with the new patch. I can't confirm this as I don't have psql access to the qastaging database, and the live db patch version number isn't in the footer.
